Composites made of chitosan are useful in food packaging applications and can be applied as edible coatings or films. The improved UV protection and moisture barrier capabilities of chitosan nanocomposites with MgO nanoparticles were also demonstrated.
Because of their improved physicochemical characteristics, the manufactured chitosan/metal oxide nanocomposite films could be employed as a component of food packaging. Due to its antibacterial qualities, chitosan has been utilised extensively in antimicrobial films, to provide edible protective coating, dipping, and spraying for food products.
The Global Chitosan-based packaging market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
An important environmental issue has been brought about by the widespread and unchecked usage of food packaging made of plastics with a petroleum base.
The food packaging business must therefore create packaging made of biodegradable polymers. One of the most prevalent polysaccharides in nature, chitosan is one of the many raw materials examined in the literature. Chitosan’s non-toxicity, antibacterial, and antifungal qualities have garnered attention.
Chitosan is regarded as an excellent substance for the creation of food-use films as a result. While intelligent packaging keeps track of the state of packaged food or the environment in which it is stored, active packaging maintains or enhances the condition of packaged food or increases its shelf life.
Chitosan-based films’ mechanical, barrier, and functional properties have been evaluated in relation to the impact of the inclusion of active chemicals.
The antibacterial and antioxidant properties of these active and intelligent composite films, as well as their prospective applications, have also been updated. According to published research, phenolic chemicals enhance the mechanical and barrier properties of chitosan films.
The inclusion of essential oils, phenolic compounds, and other fruit extracts dramatically increased the antibacterial and antioxidant ability of the films. There has been a lot of research done on chitosan-based films with intelligent pH indicators.
To better understand the types of foods that might come into touch with chitosan packaging, more research on the material and its interactions with other substances is required.
